I A L VII ATTORNEY Pa tent dJan; 6, 1931 OFFICE 1 ram EZELL GRAY, or HoLnENvILLE, OKLAHOMA ADJUSTABLE BRACE 7 Application filed September 4; 1929. Serial No. 390,366.

,This invention relates to a brace which is adjustable as to its length, the general object of the invention being to form the brace of -two telescopic parts, with a threaded shaft located in one part and engaging a nut'carried by the other part, with manually operated means whereby the shaft can be turned to adjust the two parts and thus increase or decrease the length of the brace.

, Another'object of the invention is to provide each end of the'brace With adjustable shoes for engaging the parts to be braced by the device. v r f This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully de'scribed illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several vlews, and 1n wh1c'h:-

Figure 1 is an elevation of the device. 7 Figure 2 is a side view thereof. Figure 3 is a section on line 33 of Figure 1. g I V s Figure/l: is a section on'line 44 of Figure1-.-

In these views, the numeral'l indicates one member of the brace, and 2 the other member which slides within the first member. A block 3 is adjustably fastened within the member 1 by means of thebolts 4 which pass through the block and through any one of a plurality of pairs of holes 5 formed in opposing faces of the member 1. A threaded shaft 6 has one end sw'iveled in the block and its other endpassesthrough a nut 7 fastened in the inner endof the member 2. The shaft has a worm gear 8 thereon whichis engaged by aworm 9 on a stub shaft 10 which is rotat- "ably supported by the hangers 11 on theblock 3; This shaft 10 is formed with a;

wrench receiving'head which is engaged by a wrench passing through any one of a number of holes 12 formed in one side of the member 1, these holes 12 being so arranged with relation to the holes 5 that a ,hole 12 provided that such changes fal block and having a worm thereon the worm gear of the first shaft, the

row'being curved, as shown in F igure 1. Each shoe is provided with a substantially V-shaped recess 17 for engaging the member to be braced. Of course, the-shoes can be provided 7 with other shaped recesses, if desired.

From the foregoing it will be seen that the brace can be adjusted as to its length by turning the shaft 10to rotate the shaft 6 to cause the said shaft 6 to move the members 1 and 2 outwardly or inwardly. It will also be seen that the block 3 can be adjusted in the member 1 byplacing the'bolts 4: in the desired holes 5 in said member 1.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

Itis to be understood that changes may be made in the construction and in the combination and arrangement of the several parts,

1 within the scope of the appended claim. i

What I claim is V A device of the; class described comprising a pair o f members telescopically arran'gedya block arranged in one member, a screw shaft rotatably supported by the block, a nut carried by the other member and through which the shaft passes, a worm gear on the shaft, a

manually operated shaft supported by. the r engaging block carrying member havinga; plurality of holes therein and bolts passing. through some of the holes and through the block for adjustably connecting the block with the member and said last named member having a plufrality of holes therein for-permitting a tool to be inserted to engageithe worm shaft to i turn the same. 7 V

In testimony whereof I afiix my signature;
